Will it also allow decompression of the said archive types? Distribute 
has some utility code to handle zip/tar archives. So does PyPM. This is 
because the `tarfile` and `zipfile` modules do not "just work" due to 
several issues.

See http://gist.github.com/279606

Take note of the following in the above code:

  1) _ensure_read_write_access
  2) *File.is_valid
  3) ZippedFile.extract ... issue 6510
  4) ZippedFile.extract ... issue 6609
  5) TarredFile.extract ... issue 6584
  6) The way unpack() detects the unpacked directory.
